TCS set to overtake Infosys

2013-01-21T21:01:00.001-08:00

Tata Consultancy Services, India’s number one information technology services company, could overtake Infosys to become the most profitable one for the first time on a full-year basis in 2012-13. The Mumbai-headquartered company is already ahead of Infosys on operating profit margin in the second and third quarters; in the first quarter, it was just 10 basis points (bps) less. In the first three quarters of FY13, TCS’ average profit margin at 27.18 per cent is about 51 bps higher than that of Infosys. For the fourth quarter ending March 31, Infosys has already hinted the onshore pay rise it effected last quarter would impact the margins by about 100 bps. This could mean TCS will continue to maintain its leadership in profitability, making it the most profitable IT services company in India.

“I think TCS has a much better visibility on their business overall and it is able to plan for the long term in a steady manner, which obviously then keeps costs under control vis-a-vis Infosys. In the case of Infosys, for whatever internal reason, lack of stability in the growth is hurting their ability to not just manage costs but also to manage revenues,” said Partha Iyengar, vice-president at Gartner, the research and analyst firm. In Q2 and Q3, TCS’ operating margins were 26.75 and 27.3 per cent, respectively, as compared to Infosys’ 26.34 per cent and 25.68 per cent. In the quarter ended December 31, TCS improved its operating margin by about 55 bps, whereas Infosys saw it declining by 66 bps. According to some observers, the fact that Infosys has started to compromise on its profit margin could mean that the company is now investing back to the business more than before. It also indicates the company might have become more aggressive in contracting terms and pricing, to gain market share and volume. Traditionally, Infosys is known as a premium player in pricing. “We don't see them (Infosys) giving pricing discounts, though they have become more flexible and responsive in contracting terms with clients. They have started to spend a little more on sales and marketing, which might have added to their costs,” said Sudin Apte, chief executive & research director of offshore advisory firm Offshore Insights. In a meeting with analysts towards the end of last month, Infosys had indicated the company was becoming aggressive on pricing to drive volume growth. Analysts at an equity research company said Basab Pradhan, head of sales & marketing, alliance functions at Infosys, had confirmed the change in strategy. In an interview to Business Standard in August last year, S Gopalakrishnan, executive co-chairman of Infosys, had also said pricing was becoming a major driver in acquiring newer clients. “We are sensitive to the environment and we are sensitive that cost is a primary driver today. But we don’t want to position ourselves as the lowest-cost provider. We want to be competitive in the market in terms of total cost of ownership,” he had said.

22. Any serious policy discussion about acceptable levels of risk in connection with explosions is not well served if the participants fail to use the word “explosion” and use the phrase “energetic disassembly” instead. In fact, the word “explosion” elicits desirable reactions, such as a heightened level of attention, whereas the substitute phrase does not. Therefore, of the two terms, “explosion” is the one that should be used throughout discussions of this sort.
Which of the following is an assumption on which the argument above depends?
(A) In the kind of discussion at issue, the advantages of desirable reactions to the term “explosion” outweigh the drawbacks, if any, arising from undesirable reactions to that term.
(B) The phrase “energetic disassembly” has not so far been used as a substitute for the word “explosion” in the kind of discussion at issue.
(C) In any serious policy discussion, what is said by the participants is more important than how it is put into words.
(D) The only reason that people would have for using “energetic disassembly” in place of “explosion” is to render impossible any serious policy discussion concerning explosions.
(E) The phrase “energetic disassembly” is not necessarily out of place in describing a controlled rather than an accidental explosion

4 The total expense of a boarding house are partly fixed and partly variable with the number of boarders. The charge is Rs.70 per head when there are 25 boarders and Rs.60 when there are 50 boarders. Find the charge per head when there are 100 boarders.

a) 65
b) 55
c) 50
d) 45

Solution:
Let a = fixed cost and k = variable cost and n = number of boarders
total cost when 25 boarders c = 25*70 = 1750 i.e. 1750 = a + 25k
total cost when 50 boarders c = 50*60 = 3000 i.e. 3000 = a + 50k
solving above 2 eqns, 3000-1750 = 25k i.e. 1250 = 25k i.e. k = 50
therefore, substituting this value of k in either of above 2 eqns we get
a = 500 (a = 3000-50*50 = 500 or a = 1750 - 25*50 = 500)
so total cost when 100 boarders = c = a + 100k = 500 + 100*50 = 5500
so cost per head = 5500/100 = 55

5. Amal bought 5 pens, 7 pencils and 4 erasers. Rajan bought 6 pens, 8 erasers and 14 pencils for an amount which was half more than what Amal had paid. What % of the total amount paid by Amal was paid for pens?

a) 37.5%
b) 62.5%
c) 50%
d) None of these

Solution
Let, 5 pens + 7 pencils + 4 erasers = x rupees
so 10 pens + 14 pencils + 8 erasers = 2*x rupees
also mentioned, 6 pens + 14 pencils + 8 erarsers = 1.5*x rupees
so (10-6) = 4 pens = (2-1.5)x rupees
so 4 pens = 0.5x rupees => 8 pens = x rupees
so 5 pens = 5x/8 rupees = 5/8 of total (note x rupees is total amt paid byamal)
i.e 5/8 = 500/8% = 62.5% is the answer

6. lost Rs.68 in two races. My second race loss is Rs.6 more than the first race. My friend lost Rs.4 more than me in the second race. What is the amount lost by my friend in the second race?

Solution:
x + x+6 = rs 68
2x + 6 = 68
2x = 68-6
2x = 62
x=31
x is the amt lost in I race
x+ 6 = 31+6=37 is lost in second race
then my friend lost 37 + 4 = 41 Rs

36. There are 4 balls and 4 boxes of colours yellow, pink, red and green. Red ball is in a box whose colour is same as that of the ball in a yellow box. Red box has green ball. In which box you find the yellow ball?

Ans : green...

Solution: Yellow box can have either of pink/yellow balls.
if we put a yellow ball in "yellow" box then it wud imply that "yellow" is also the colour of the box which has the red ball(becoz acordin 2 d question,d box of the red ball n the ball in the yellow box have same colour)
thus this possibility is ruled out...
therefore the ball in yellow box must be pink,hence the colour of box containin red ball is also pink....
=>the box colour left out is "green",,,which is alloted to the only box left,,,the one which has yellow ball..
------------------------------------------------------------------------------------------------------------

so between 1 to 100 there are 10 nos like 5,15,25,..,95 which has 5 in unit place.
Similarly for every no divisible by 10 one zero is added in the answer so between 1 to 100 11 zeros are added
for 25,50,75 3 extra zeros are added
so total no of zeros are 10+11+3=24

42. Anand finishes a work in 7 days, Bittu finishes the same job in 8 days and Chandu in 6 days. They take turns to finish the work. Anand on the first day, Bittu on the second and Chandu on the third day and then Anand again and so on. On which day will the work get over?

a) 3rd
b) 6th
c) 9th
d) 7th

Ans : 7th day

Solution: In d 1st day Anand does 1/7th of total work
similarly,
Bithu does 1/8th work in d 2nd day
hence at d end of 3 days, work done = 1/7+1/8+1/6=73/168
remaining work = (168-73)/168 = 95/168
again after 6 days of work, remaining work is = (95-73)/168 = 22/168
and hence Anand completes the work on 7th day.

Alice starts and the players take turns. A turn consists of moving the coin on the top to a position i below the top coin (0 = i = 100). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2-move.
If the gold coin happens to be on top when it’s a player’s turn then the player wins the game.

A. Alice has no winning strategy.
B. Initially, the gold coins the third coin from the top. Then

Interview Question 6 :

2) What is the difference between a = ++b and a = b++ ?

Answer :

The first statement a = ++b can be broken down into two statements b = b + 1 followed by a = b. Hence b will be incremented first and will be assigned to a. Hence values of a and b will be same at the end.

The second statement a = b++ can be broken down into two statements a = b followed by b = b + 1. Hence b will be assigned to a. Only after this assignment b will be incremented. Hence values of a and b will be different at the end.

Question 1

12 leading companies were brought into an issue in deciding about the allocation of land related properties by a Government agency. The companies were numbered from 2 to 12. Among these the companies numbered 7,9 and 10 were three leading business rivals. It was decided to use two dice and bet on the numbers emerging out of such throws. It was seen that results range from 2 to 12. Out of such throws which of the following: 7 or 9 or 10 is likely to appear more often than the other numbers? (i.e will any of the companies will have advantage over the others with the method followed.)

a) 10 b) 9 c) 7 d) all are equally possible.

Answer : c) 7

Solution :

Let (x,y) represent any throw of a dice where x represents number of I dice and y represents number on II dice
When two dice are thrown possible occurences of 7 include : (1,6), (6,1), (2,5) (5,2) (3,4), (4,3)
When two dice are thrown possible occurences of 9 include : (3,6),(6,3) (4,5) (5,4)
When two dice are thrown possible occurences of 10 include : (5,5) , (5,5)
Sum 7 can appear in at least 6 combinations as against 9 which occurs in 4 combinations and 10 which occurs in 2 combinations. Hence company 7 should have more chances of winning the bid over the others.
------------------------------------------------------------------------------------------------------------
Question 2

Three school friends studying in a Higher Secondary School studying in standard 10, 11 and 12 repectively met in a leading five star hotel in a tea party. During discussions they had an argument about the chances of getting specific numbers by the throw of 2 dice. Which two numbers from 9,10 and 11 will have equal chances of appearing.

a) 9,10 b) 10,11 c) 9,11 d) none of the above

Answer : b) 10,11

Solution :

The solution to this question is very similar to that of the first question.
When two dice are thrown possible occurences of 9 include : (3,6),(6,3), (4,5) (5,4)
When two dice are thrown possible occurences of 10 include : (5,5), (5,5)
When two dice are thrown possible occurences of 11 include : (5,6), (6,5)
Therefore 9 can appear in 4 possible combinations, 10 can appear in 2 possible combinations and 11 can appear in 2 possible combinations. Therefore numbers 10 and 11 have equal chances of appearing during the throw of two dice.
------------------------------------------------------------------------------------------------------------
Question 3

Mrs. Kalyani Chatterjee of Bhubaneshwar went abroad and settled in USA about twenty years ago. She returned on an holiday trip to Bhubaneshwar and went to Konarak Sun Temple for sightseeing. To her surprise she met ten of her class mates at Konarak . What is the probability that at least one of the ten people she met has the same birth day as that of Mrs.Kalyani Chatterjee. Her birth day – 14th March.

a) 0.0028 b) 0.014 c) 0.128 d) none of these.

Answer : a) 0.0028.

Solution :

Probability of a friend having birthday on same date as that of Kalyani = 1/365

Probability of a friend not having birthday on same date as that of Kalyani = 1 - 1/365 = 364/365

Probability of 2 friends not having birthday on same date as that of Kalyani = (364/365).(364/365) = (364/365)2

Similarly Probability of n friends not having birthday on same date as that of Kalyani = (364/365)n

Now, Probability of n friends having birthday on same date as that of Kalyani = 1 - Probability of n friends not having birthday on same date as that of Kalyani
= 1 - (364/365)n

Substituting n = 10 in above formula we get,

1 - (364/365)10 = 0.0028

Question 3

Three students of Victory Engineering College - Saravanan, Meenakshi and Mangesh were given a mathematics problem. If their chances of solving the problem are 60%, 50% and 40%, what is the probability the problem will be solved?

a) 0.33 b) 0.66 c)0.77 d) 0.88

Answer : d) 0.88

Solution :

For solving such problems one has to employ the below simple equation :
P(problem is solved) = 1 – P(problem is not solved)
In other words, P(problem is solved) = 1 – P(none of the students solve the problem) -> eq 1
But probability of no one solves the problem can be found using the below equation
P(none of the students solve the problem) = P(Saravanan being not able to solve) x P(Meenakshi being not able to solve) x P(Mangesh being not able to solve)

= [1 - P(Saravanan solving the problem)] x [1 - P(Meenakshi solving the problem)] x [1 - P(Mangesh solving the problem)]
P(none of the students solve the problem) = [1 - 0.6][1 - 0.5][1 - 0.4] = .4 x .5 x .6 = .12 -> eq 2
Substitute the value for P(none of the students solve the problem) from eq 2 in eq 1, we get :
P(problem is solved) = 1 – 0.12 = 0.88
------------------------------------------------------------------------------------------------------------
Question 4

The New College, Chennai conducted NCC shooting camp at St. Thomas Mount. Students were asked to participate in the shooting competition. Four students – Goutham, Malavika, Geetha and Vinya participated in the competition. If the probability of their hitting the target Apple correctly is 0.7, 0.6, 0.5 and 0.4 respectively, what is the probability that four shots aimed at the target will hit correctly?

a) 0.964 b) 0.624 c) 0.824 d)0.756

Answer : a) 0.964

Solution :

The target Apple will be brought down even if one of the four shots hit the target.
The opposite of this is the situation when none of the shoots hit the target.
The probability of none of the shoot hits the target = P(Goutham missing the target) x P(Malavika missing the target) x P(Geetha missing the target) x P(Vinya missing the target)

= [1 - P(Goutham hitting the target)] x [1 - P(Malavika hitting the target)] x [1 - P(Geetha hitting the target)] x [1 - P(Vinya hitting the target)]
(1-0.7)(1-0.6)(1-0.5)(1-0.4)=0.3*0.4*0.5*0.6=0.036

So, the probability that at least one of the shoots hits the target Apple = 1 - probability of none of the shoot hits the target = 1 – 0.036 = 0.964.
------------------------------------------------------------------------------------------------------------
Question 5

In the tenth standard class of St.Michael’s School, Palayamkottai, 30% of the students were offered Tamil, 20% were offered Telugu and 10% were offered both. If a student is selected at random, what is the probability that he has offered Tamil or Telugu?

a) 2/5 b) 3/4 c) 3/5 d) 3/10

Answer : a) 2/5.

Solution :

P(Student offered Tamil) = Students offered Tamil / Total Students = 30/100 = 3/10,

P(Telugu) = Students offered Telugu / Total Students = 20/100 = 1/5

And P (Students offered both Tamil and Telugu) = P(Tamil Ω Telugu) = 10/100 = 1/10

Probability that a selected student at random has been offered Tamil or Telugu can be found by the below simple formula

P(Tamil or Telugu) = P (Tamil U Telugu) = P(Tamil) + P(Telugu) - P(Tamil Ω Telugu)
= (3/10 + 1/5 - 1/10) = 4/10 = 2/5
------------------------------------------------------------------------------------------------------------
Question 6
A company has three staff members working in communications department. They are Peter, Satish and Raju. The company has received a work of sending communication to its potential customers. The time the three take to complete the dispatch work together is 2 days less than Peter would have taken to do it alone, 10 days less than Satish to do the work alone and one-third of the time that Raju would have taken working alone. How many days will the three people take to do the dispatch of all the mails working together?

a) 2 days b) 4 days c) 5 days d) 3 days

Answer : a) 2 days.

Solution :

Let the number of letters to be dispatched be X.
If the three people together take ‘D’ days to complete the work then
Peter will take (D +2) days to complete it alone.
Satish will take (D + 10) days to complete it alone.
And Raju will take 3 D days to complete it alone.
Speed of Peter --- X / (D+2) letters per day
Speed of Satish -- X / (D + 10) letters per day
Speed of Raju -- X / 3D letters per day

All of them working together for one day will dispatch –
X/(D+2) + X/(D+10) + X/3D letters -> eq 1
Number of days it will take for them to complete the dispatch of all the X letters = X / Letters that can be dispatched by all of them in one day = X / [ X/D+2 + X/D+10 + X/3D]
But we had assumed the number of days to dispatch all X letters as D.
Therefore, D = X / [ (X/D+2) + (X/D+10) + (X / 3D)]
Or X/D = (X /D+2) + (X/D+10) + (X/3D)
Or 1/(D+2) + 1/(D+10) + 1/ 3D = 1 /D

Substituting the options one by one, we can find that D = 2 satisfies the equation.
i.e Substitute D = 2 in both sides of 1/(D+2) + 1/(D+10) + 1/ 3D = 1 /D.
Substituting D = 2 On LHS : 1/4 + 1/12 + 1/6 = 6/12 = 1/2
On RHS D = 2 we get 1/2
Therefore, LHS = RHS when D =2 and hence 2 is the right answer

Question 7

Roja and Edward were working in a courier company. Roja takes 6 hours to pack 32 parcels while Edward takes 5 hours to pack 40 parcels. How long they will take to pack 330 parcels working together ?

a) 24 hours 45 minutes b) 23 hours c) 25 hours 15 minutes d) none of these.

Answer : c) 25 hours 15 minutes

Solution :

Speed of Roja per hour = 32/6 parcels
Speed of Edward per hour = 40/5 = 8 parcels
When both of them work together in one hour they will pack
32/6 + 8 = 13 1/3 parcels
For packing 330 parcels it will take = 330 / parcels that can be packed by them in one hour = 330 / 13 1/3 = 25 hours 15 minutes

Question 8

An overseas software company entrusted the work to a company in India. The Indian company conducted campus recruitment drives and recruited men and women on a large scale. It gave training to newcomers in its training centre with advanced facilities at Mysore for over three weeks. The company conducted periodical tests to assess the progress in terms of knowledge and output of its employees in order to ensure uniform output being given by all the employees. Company’s 48 programmers wrote 48 lines of program in 36 minutes. How many programmers are required to write 192 lines program in 24 minutes.?

a) 24 b) 36 c) 288 d) 72

Answer : c) 288

Solution :

Programmers Lines Minutes
48 48 36
? 192 24
For such problems where efficiency of programmers are considered to be the same, one can employ the equation
P1 X M1 / L1 = P2 X M2 / L2 -> eq 1
Where P1,M1 and L1 are the number of programmers, minutes and lines of code respectively in I case and
P2,M2 and L2 are the number of programmers, minutes and lines of code respectively in II case.

From the question, we can find that P1 = 48, M1 = 36, L1 = 48, M2 = 24 and L2 = 192. P2 is to be found out.
Substituting the above values in equation 1 we get,
(48 x 36) / 48 = (P2 X 24)/192
Or, P2 = (48 x 36 x 192) / (48 x 24) = 288

Question 9

Ramesh Khanna was five times old as his son Kishan Khanna eight years ago. Now he is three times as old as his son Kishan Khanna. Assume they both live in a country where people understand only binary numbers and they use symbol '0' for binary 1 and '1' for binary zero. Also they add 1 before any binary number. Express Ramesh Khanna’s present age in accordance to that world

a) 1001111 b) 1001111 c) 1100011 d) 1010000

Answer : a) 1001111

Solution :

Let Ramesh Khanna’s age be represented as ‘F’ eight years ago and the age of Kishan Khanna be represented as ‘S”.
F = 5 S
F + 8 = 3 (S + 8)
5S + 8 = 3S + 24
5S – 3 S = 24 – 8
2S = 16
S = 8

Now Ramesh Khanna’s age will be 5S + 8 = (5x8) + 8 = 48
Expressed as binary 110000 . However the people in their country use symbol 0 for binary one and 1 for binary zero. Replacing 1 with 0 and 0 with 1 we get 001111. Also those people usually add 1 before any binary number. Hence the answer becomes 1001111.

Question 10

Bhavna is presently three times as old as her daughter Anushka. Ten years ago Bhavna was five times as old as her daughter Anushka was. After how many years, sum of their ages will be 100.

a) 10 b) 20 c)15 d) none of these.

Answer : a) 10

Solution :

Let Bhavna’s present age be represented as B
Let her daughter Anushka’s age be represented as A.
B = 3 A
Ten years ago,
B - 10 = 5(A – 10)
3A - 10 = 5A - 50
-10 + 50 = 5A – 3A = 2 A
40 = 2 A
A = 20.
B = 3 x A = 60.
Present sum of their ages = A + B = 80.
When 10 is added to both A and B, Sum of their ages will become 100. Hence, after 10 years, their sum of ages will be 100.
------------------------------------------------------------------------------------------------------------
Question 11

Monisha was seven times as old as her daughter Mercy eight years ago. Now three times Mercy’s age is her mother age. Before how many years the ratio of their ages (ratio of mother's age to Mercy's age) will be increased by 1 from the current ratio

a) 5 b) 4 c) 8 d) none of these.

Answer : b) 4

Solution :

Eight years ago -- let Monisha’s age be M and Mercy’s age be D.
M = 7 D
Now M + 8 = 3 (D + 8)
7 D + 8 = 3D + 24
7D - 3 D = 24 - 8 = 16
D = 4 = age of Mercy before 8 years
M = 28 = age of Mother before 8 years

Current age of Mercy = D + 8 = 12
Current age of Monisha = M + 8 = 36
Current ratio of mother's age to Mercy's age = 36/12 = 3.
Let before x years this ratio becomes 1 more than the current ratio. i.e x denotes the number of years before which the ratio becomes 3 + 1 = 4.
Then 36 - x / 12 - x = 4
36 - x = 48 - 4x
3x = 12
Or x = 4
i.e before 4 years, the ratio of their ages will be 4. Therefore answer = 4

Question 12

“Hunterkey” a leading software company situate in China was started in the year 1988. The company had been progressing well since inception and the company has achieved a turn over of over 10 billion $. The management of the company has plans for achieving greater heights in terms of turnover and has been training its members in various skills such as technical skills, soft skills, programming skills etc. 60 programmers of the company write 60 lines of programs in 60 minutes totally. How long will it take for 84 programmers to write 84 lines of programs?

a) 84 min. b) 48 min c)60 min d) 72 min

Answer : c) 60 min.

Solution:

For problems like this where efficiency of the programmers/workers are assumed constant implicitly, you can apply the below formula
P1 X M1 / L1 = P2 X M2 / L2
Here, P1,M1 and L1 are number of programmers, number of minutes and number of lines respectively in case I
And, P2,M2 and L2 are number of programmers, number of minutes and number of lines respectively in case II.
Given P1 = 60, M1 = 60, L1 = 60, P2 = 84, L2 = 84.
Substituting in above formula we get.
60 x 60 / 60 = 84 x M2 / 84.
Simplifying we get, M2 = 60 minutes.

Question 13

“Universal Software Inc.” USA is situated in California. The company was started in the year 1975 and has been progressing extremely well. It is aiming to reach the topmost position in the near future. During the year 2010, in a team, on any particular day, 48 programmers of the company were able to write 48 lines of software programs in 48 minutes. The company recruits 72 more programmers. Also the team management improves the throughput by making them to work for 72 more minutes every day. What will be the increase of the number of lines of code possible now ?

a) 300 lines b)252 lines c)48 lines d) 48 lines

Answer : b) 252 lines

Solution :

Using the same formula as in first question :
P1 X M1 / L1 = P2 X M2 / L2
Given, P1 = 48, M1 = 48 and L1 = 48
Given P2 = P1 + 72 = 48 + 72 = 120
Given M2 = M1 + 72 = 48 + 72 = 120
Substituting values in formula we get,
48 x 48 / 48 = 120 x 120 / L2
Simplifying we get L2 = 300
Increase in number of lines of code = L2 - L1 = 300 - 48 = 252

Question 14

“Extremely fast solutions” a software programmer provider has been training its manpower in such a way that 36 programmers could write 36 software programs of similar nature in 36 hours. The company has received an order for getting 84 software programs of similar nature in 24 hours. How many additional programmers should the company employ for this project?

a) 90 b)42 c)66 d)44

Answer : a) 90

Solution :

Using the same formula as in first question (Note : M1 and M2 denote time in hours and not minutes. Left hand side and Right hand side should have same units and thats the deal.)
P1 X M1 / L1 = P2 X M2 / L2
Given P1 = 36, M1 = 36, L1 = 36.
Given L2 = 84, M2 = 24
Substituting we get,
36 x 36 / 36 = P2 x 24 / 84
Or P2 = 36 x 84 / 24 = 126
Number of additional programmers = P2 - P1 = 126 - 36 = 90.

Question 15

Mohan bought a new bike. The number plate consists of 4 digits. How many 4-digit numbers can be formed for the number plate of Mohan’s bike from the digits 2, 4, 6, 7, 5 and 8 which are divisible by 5 with the condition that none of the digit is repeated?

a) 60 b) 30 c) 24 d) 120

Answer : a) 60

Solution :

Since the number on number plate is divisible by 5, the last digit should be 5 only. (0 is not allowed as per the question)
And the first digit can be filled by any of the remaining numbers (2, 4, 6, 7 and 8).
So, the number of ways of filling first digit without repetition = 5 ways
And the second digit can be filled by the remaining 4 numbers.
So, the number of ways of filling second digit without repetition = 4 ways
Therefore, number of ways of selecting 4-digit number is 5 x 4 x 3 x 1 = 60.

Question 16

A family went to a studio to take a family photo. There are 5 members in that family namely a husband and his wife and their 3 children. In how many ways they can be made to stand (arranged) to take a photo in such a way that the husband is adjacent to his wife?

a) 80 ways b) 30 ways c) 120 ways d) 60 ways

Answer : b) 30 ways

Solution :

Number of ways of placing husband = 5 ways
Since husband must be adjacent to his wife, number of ways of placing wife = 1 way (near husband)
There are three spots remaining :
Any of the three children can be made to stand in first place. Therefore there are 3 ways to fill this spot.
Any of the remaining two children can be made to stand in the second spot. Therefore there are 2 ways to fill this spot.
The third spot can be filled in one way as there will be only one child remaining.
Therefore, the number of ways of arranging the five members = 5 x 1 x 3 x 2 x 1 = 30

Question 17

Anand has to send 5 different greeting cards to his 5 friends. His five friends are located in Chennai, Mumbai, Bangalore, Delhi and Mysore. In how many ways he can send the greetings to his friends such that no friend is getting 2 greeting cards?

a) 80 ways b) 30 ways c) 120 ways d) 60 ways

Answer : c) 120 ways

Solution :

The number of ways of sending the first greeting card is 5 ways
Since no friend has to get two greeting cards,
The number of ways of sending the second greeting card is 4 ways.
The number of ways of sending the third, fourth and the fifth greeting card are 3 , 2 and 1 ways.
Hence the number of ways of sending all the 5 greeting cards = 5 x 4 x 3 x 2 x 1 = 120 ways

Question 18

Four years ago, the average age of Deena and Prakash was 21 years. With Harish joining then now the average becomes 25 years. How old is Harish now?

a) 28 years b) 26 years c) 24 years d) 25 years.

Answer : d) 25 years.

Solution:

Let the present age of Deena, Prakash and Harish be A, B and C respectively.
4 years ago, the average age of Deena and Prakash was 21 years.
(i.e.) (A - 4 + B - 4) / 2 = 21
=> A + B = 50 -------- (1)
But now, the average age of Deena, Prakash and Harish is 25 years.
(i.e.) (A + B + C) / 3 = 25
=> A + B + C = 75 ------- (2)
(2) – (1) => C = 75 - 50 = 25.
Hence, the Present age of Harish is 25 years.
------------------------------------------------------------------------------------------------------------
Question 19

The present age of Harini’s father is 4 times the present age of Harini. And the age difference of Harini’s father and mother is 5 years. Five years ago, the sum of all the three person’s age was 70 years. What is the present age of Harini’s father?

a)44years b) 40years c) 50years d) 48years

Answer : b) 40

Solution:

Let the Present ages of Father, Mother and Harini be F, M and H respectively.
Present age of Father = 4 * Present age of Harini
i.e. F = 4H ------- (1)
Age difference between Harini’s Parent's = 5
i.e. F – M = 5 -----------(2)
Five years ago, the sum of ages of Father, Mother and Harini is 70 years
i.e. F – 5 + M – 5 + H – 5 = 70
=> F + M + H = 85 -------- (3)
(2) + (3) => 2F + H = 90 ----- (4)
Substitute (1) in (4), we get H = 10.
Then F = 4*10 = 40.
Therefore the present age of Harini’s father is 40 years.

Question 20

Haritha told her friends that if she add ten times her age ten years from now to five times her age five years ago is same as the 20 times of her current age. How old Haritha will be ten years from now?

a)15 years b) 20 years c) 23 years d) 25 years

Answer : d) 25 years

Solution:

Let the age of Haritha be X.
Then, 10 times her age after 10 years + 5 times her age before 5 years = 20 times her present age.
i.e. 10 * (X + 10) + 5 * (X - 5) = 20 * X
15X + 75 = 20X
5X = 75
X = 15
Hence, Haritha’s Present age is 15 years.
So, after 10 years, Haritha’s age will be 25 years.
------------------------------------------------------------------------------------------------------------
Question 21

Three years ago, the ages of Geetha, Reena and Surya are in the ratio of 3:4:5. Three years hence, the sum of their ages is 78. What is the age of Reena at present?

a)18 years b) 23 years c) 28 years d) 20 years

Answer : b) 23 years

Solution:

Let the ages of Geetha, Reena and Surya 3 years ago be 3X, 4X and 5X respectively.
After 3 years, the sum of their ages is 78.
i.e. (3X + 3) + 3 + (4X + 3) + 3 + (5X + 3) + 3 = 78
12X = 60
X = 5.
Hence, Reena’s present age is 4X + 3 = 4(5) + 3 = 23 years.

Question 22

Two countries - Germany and France are participating in a hockey game. Mr. Randor Guy, the famous astrologer in Germany is able to predict the winner of each match with great success. It is rumoured that in a match between 2 teams X and Y,Rando Guy picks X with the same probability as X's chances of winning. Let's assume such rumours to be true and that in a match between Germany and France, Germany the stronger team has a probability of 7/10 of winning the game. What is the probability that Randor Guy will correctly pick the winner of the Germany - France game?

a) 0.58 b) 0.68 c) 0.82 d) 0.42

Answer : a) 0.58

Solution :

Randor Guy predicts the winner in games with the same probability of winning. --> statement I
Germany has got a chance of winning the game with 7/10 probability. France has got a chance of winning the game with 3/10 probability.
Probability of Randor Guy picking the Germany correctly is 7/10 while picking France is 3/10 (as per statement I).

Probability of Randor Guy picking the winning team correctly = (Probability of Germany winning the game) AND (Probability of Randor Guy picking Germany correctly) OR (Probability of France winning the game) AND (Probability of Randor Guy picking France correctly).

Note : In probability related formulas generally AND translates to x and OR translates to +

Therefore, Probability of Randor Guy picking the winning team correctly = (Probability of Germany winning the game) * (Probability of Randor Guy picking Germany correctly) + (Probability of France winning the game) * (Probability of Randor Guy picking France correctly).
Probability of predicting winning team = (7/10 * 7/10) + (3/10 * 3/10)
=0.58

Question 23

A box has 45 chocolates of different colours 20 red, 15 white and 10 black chocolates. If a chocolate is chosen at random, what is the probability of that being white chocolate?

a) 1/2 b) 1/3 c) 2/3 d) 3/4

Answer : b) 1/3

Solution :

Note : This is a simplest of the simple questions that you can expect on probability. This is a usual case in placement tests. You should be able to identify such simple questions amidst tough questions. At times, you could get mislead by thinking this is a tricky one.

Any of 45 chocolates could be chosen. So, totally there are 45 possibilities. Since there are only 15 white chocolates, only 15 possibilities can lead to a white chocolate. Hence P(white chocolate) = 15/45 or 1/3.

Question 24

In an off campus placement programme, a software company recruiter interviewed 75 prospective candidates -- 10 from Civil engineering department, 5 from Bio-chemical department and rest from computer science department. If the software company finally issued offer letter to 17 candidates, what is the probability that all the selected candidates belonged to only computer science department?

a) 60C17/ 75C17 b) 65C17/75C17 c) 70C17/75C17 d) None of these.

Answer : a) 60C17/75C17

Solution :

17 out of 75 candidates selected in 75C17 ways. 17 out of 60 from computer science department can be selected in 60C17 ways.
So the required probability = Ways of selecting 17 computer science candidates / Ways of selecting 17 candidates from all departments
= 60C17 / 75C17

Question 25

Chandrasekaran worked very sincerely in the software company which selected him in the campus recruitment. At the end of the first year he was given a salary increase of 5%. In the second year another friend from his college also joined the company and they spent more time together. As a result of this performance of Chandrasekaran came down in terms of the team leader. The team leader recommended a cut of 2.5% from the salary of Chandrasekaran. In the third year at the end of the first month he received Rs.34398 as salary and felt aggrieved. He started thinking about resigning from this company and try for other companies which pay a higher salary. What was the salary of Chandrasekaran at the beginning of first year?

a) Rs.32400 b) Rs.36800 c) Rs.22000 d) Rs.33600

Answer : d) Rs. 33600

Solution :

Let the salary at the beginning of first year be Rs.X
At the beginning of second year it will then be 5% more than his beginning salary. Therefore his second year salary = 105% of X = 105X/100
On this 2.5% reduction , his salary now will be 2.5% lesser than his second year salary = 97.5% x Second Year Salary = (97.5/100)(105X/100) – But this value is given as Rs.34398
Solving (97.5/100)(105X/100) = 34398, we get,
X = 34398 x 100 x 100 divided by 105 x 97.5
= Rs. 33600

Question 26

Miss. Ranjitha bought a new wall clock which rings at every one hour. At 3 O’ clock the clock ticks 3 times and at 4 O’ clock the clock ticks 4 times. At 4 O’ clock the time between the first tick and the last tick is 21 seconds. How long does it tick at 12 O’ clock?

a) 66 seconds b) 55 seconds c) 77 seconds d)44 seconds

Answer : c) 77 seconds

Solution :

This is a simple problem. The gap between the first tick and the last tick at 4 O' clock is 3 gaps. Time taken = 21 seconds. That means between two gaps it takes 7 seconds.
At 12 O clock there will be 11 gaps. Total time for 11 gaps = 77 seconds.
Though the question could look confusing at first, this is actually a very simple questions. With practice, you should be ready to identify these kinds of questions which could potentially save a lot of your time during tests.

Question 27

Anushka has a jewel chest containing Rings, Pins and Ear-rings. The chest contains 26 pieces. Anushka has 2 1/2 times as many rings as pins, and the number of pairs of ear rings is 4 less than the number of rings. How many earrings does Anushka have?

a) 12 b)8 c)6 d)10

Answer : a) 12

Solution :

Assume that there are R rings, P pins and E pair of ear-rings.

It is given that, she has 2 1/2 times as many rings as pins.
R = (5/2) * P or P = (2*R)/5

And, the number of pairs of earrings is 4 less than the number of rings.
E = R - 4 or R = E + 4

Also, there are in total 26 pieces.
R + P + 2*E = 26
R + (2*R)/5 + 2*E = 26
5*R + 2*R + 10*E = 130
7*R + 10*E = 130
7*(E + 4) + 10*E = 130
7*E + 28 + 10*E = 130
17*E = 102
E = 6

Hence, there are 6 pairs of Ear-rings i.e. total 12 Ear-rings

Question 1

There are three brothers x,y and z. If z's age is as much more than y's as y's age is more than x's age, find by how much percentage y is older than x. Hints: Age of z is 20 and y is 5 years older than x.

a. 100% b. 50% c. 25% d. 75%

Answer : b. 50%

Solution.:

Let a,b and c be the ages of x,y and z respectively.

It is given that z's age is as much more than y's as y's age is more than x's age.

Writing the above statement in the form of an equation, we get

c - b = b - a ...(1)

It is given that age of z i.e c = 20

Substituting c = 20 in eq 1 we get,

20 - b = b - a

20 = 2b - a ...(2)

It is also given that y is 5 years older than x. This implies b - a = 5 or b = a + 5...(3)

Substitute b = a + 5 in eq 2 we get,

20 = 2a + 10 - a

20 = a + 10 or a = 10

Substitute a = 10 in eq 3 we get

b = 15

Percentage by which b is more than a is (b - a)/a x 100% = (15 - 10)/10 x 100 = 50%
------------------------------------------------------------------------------------------------------------

Question 2

John is 100% older than Johan. 20 years hence, John will be 50% older than Johan. Can you find their ages.

a. 30,20 b. 40,20 c. 60,40 d. 50,10

Answer : b. 40,20

Solution :

Let age of John be b.
Let age of Johan be a.

Currently John is 100% older than Johan. This implies b - a/a = 100%

Or (b - a)/a = 1 ( this is because, 100% = 100/100 = 1)

Or b - a = a
Or b = 2a ...(1)

20 years later ages of John and Johan will be b + 20 and a + 20 respectively

After 20 years John will be older by 50%

i.e (b + 20)-(a+20)/(a+20) = 50% = 1/2

(b - a)/ (a + 20) = 1/2

Or 2b - 2a = a + 20
Or 2b = 3a + 20 ...(2)

Substitute 1 in 2 we get

4a = 3a + 20 or a = 20.

Substitute a = 20 in eq 1 we get

b = 40

John's age is 40 and Johan's 20.
------------------------------------------------------------------------------------------------------------

Question 3

Let a,b and c be ages of three brothers. b's age is greater than the sum of ages of a and c. After 7 years, by how much percentage b will be more than the sum of ages of a and c ?

a. (b - a - c - 7) / (a + c + 14) x 100% b. (b - a - c + 7) / (a + c + 14) x 100% c. (b - a - c) / (a + c + 7) x 100% d. (b - a - c - 7) / (a + c + 7) x 100%

Answer : a. (b - a - c - 7) / (a + c + 14) x 100%

Solution :

Percentage by which b's age will be greater than sum of a's and c's ages after 7 years

= Age of b after 7 years - (sum of ages of a and c after 7 years)
------------------------------------------------------------------------------------ x 100%
sum of ages of a and c after 7 years

= b + 7 - (a + 7 + c + 7)
--------------------------------- x 100%
a + 7 + c + 7

Question 4

Suresh Raina and Gautam Gambhir after a scintillating IPL match decide to travel by cycle to their respective villages. Both of them start their journey travelling in opposite directions. Each of their speeds is 6 miles per hour. When they are at a distance of 50 miles, a housefly starts flying from Suresh Raina's cycle towards Gautam Gambhir at a relative speed of 17 miles per hour with respect to Raina's speed. What will be the time taken by housefly to reach Gambhir?

(a)15 hours (b)10 hours (c) 50 hours (d)25 hours

Answer : b)10 hours

Solution:

Since Raina and Gambhir are travelling in opposite directions, Gambhir's Relative speed with respect to Raina's = Speed of Raina + Speed of Gambhir = 6 + 6 = 12 miles per hour.
Now housefly starts from Raina's cycle and travels towards Gambhir's cycle at 17 miles per hour.
Relative speed of housefly with respect to Gambhir = Speed of housefly with respect to Raina - Speed of Gambhir with respect to Raina = 17 - 12 = 5 miles per hour
Time taken for housefly to reach Gambhir = Distance to catch up / Relative speed of housefly with respect to Gambhir = 50/5 = 10 hours.

Question 5

Pinky and Ponky decided to have a car race. Initially Pinky was 20 miles behind Ponky’s car. Both of them took the race in the same direction along the same route. Pinky was travelling at a constant speed of 68 miles per hour, while Ponky was travelling at a constant speed of 60 miles per hour. How many hours will it take for Pinky to overtake and drive 8 miles ahead of Ponky?

(a)1.7 hours (b)2.0 hours (c)2.5 hours (d)3.0 hours (e) 3.5 hours

Answer : e) 3.5 hours

Solution:

It is to be understood from the problem, that Pinky has to travel 20 miles first to catch up Ponky. Then, he has to travel an additional 8 miles to be ahead of Ponky. Pinky has to travel a total of 28 extra miles relative to Ponky’s car.
Relative Speed of Pinky with respect to Ponky = 68 - 60 = 8 miles per hour.
Time taken for Pinky to cover 28 extra miles compared to that of Ponky = Extra Distance / Relative Speed of Pinky with respect to Ponky = 28/8 = 3.5 hours.

Question 6

Eveson was working for a multinational company. The pressure of work in the company was too heavy due to seasonal sales. Eveson decided to go weekend trip with his wife for relaxation. Husband and wife decided that the proposed trip should not exceed 8 hours driving in a day. They decided to maintain the average Speed of forward journey to 40 mph. Due to traffic on Sundays the return journey average speed can only be at 30 mph. How far the couple can select a picnic spot?

(a)142 Miles (b)200 Miles (c)137 Miles (d)220 Miles

Answer : c)137 Miles

Solution:

If x and y are the speeds corresponding to forward and return journeys, then average speed of the entire journey can be found using the formula : 2xy / x+y
In our case the rate for onward journey is given as 40 mph and rate for return journey is given as 30 mph
Hence average speed = 2x40x30 / 40+30 = 2400 / 70 = 240 / 7 mph
Total Travel Time is 8 hours. So total distance the couple can plan = Average Speed x Affordable Total Time = 240 / 7 x 8 =1920 / 7 = 274 miles (approximately)
Since 274 miles should be the total distance that can be covered including forward and return journeys, the picnic spot has to be at 274 / 2 = 137 miles approximately.

Question 7

Rambabu is driving a Honda Unicorn Power bike at 80 km per hour. However being sugar patient, Rambabu could not travel continuously. He takes small breaks each of 2 minutes for every 15 minute of his drive. How much distance Rambabu will cover in 90 minutes?

a)118Km b)89Km c)112Km d) 104km

Answer : d) 104km

Solution:

For every 15 minutes he takes a rest for 2 minute.
Hence for 90 minutes of drive he would require 12 minutes of rest. In effect he will be traveling for 90 - 12 = 78 minutes.
For 60 minutes he covers 80 Km.
For 1 minute he would cover 80/60 Km.
For 78 minutes he would cover (80/60)78 = 104 Km

Question 8

Priya was presented with new brand watch, as marriage anniversary gift by her husband. She observed, that the two hands of the new watch coincide every 64 minutes. She was trying to calculate, how many minutes the watch will lose per day. Can you guide Priya?

(a)32 8/11 (b)36 5/11 (c) 90 minutes (d) 96 minutes

Answer : a)32 8/11

Solution:

55 min spaces are gained by minute hand (with respect to hour hand) in 60 min. (In 60 minutes, hour hand will move 5 spaces while the minute hand will move 60 spaces. In effect the space gain of minute hand with respect to hour hand will be 60 - 5 = 55 minutes.)

In 60 min it will gain ,
60/55 x60 =65 5/11 min.

But minute hand of Priya's watch gains only 64 minutes (it is slow than normal)
Actual loss=65 5/11 -64 =1 5/11 = 16/11min

In 64 min. the loss is 16/11 min
In 24 hours the loss is = (16/11 x1/64 x24 x60)min =32 8/11 minutes.
------------------------------------------------------------------------------------------------------------
Question 9

It was 4’o clock in the evening. Shilu was staring at the new watch that was presented by her Dad two day's ago. She was trying to measure the exact time between 4 and 5’o clock during which the hands of the watch point in opposite directions forming a straight line. What would be that time?

(a) 45 minutes past 4 (b)40 minutes past 4 (c) 50 4/11 minutes past 4
(d)54 6/11 minutes past 4.

Answer : d)54 6/11 minutes past 4.

Solution:

At 4’o clock the hands are 20 minutes apart.To form a straight line in opposite direction the hands must be in 30 minutes apart. To accomplish this the minute hand have to close up the 20 minutes separation and after crossing the hour hand it has to gain 30 minute separation. In total minute hand will have to gain 20 + 30 = 50 minutes spaces apart.

55 min spaces are gained in 60 min. (In 60 minutes, hour hand will move 5 spaces while the minute hand will move 60 spaces. In effect the space gain of minute hand with respect to hour hand will be 60 - 5 = 55 minutes.)

50 min spaces can be gained in 60/55 x50 = 54 6/11 minutes.
Hence the answer is 54 6/11 minutes past 4
------------------------------------------------------------------------------------------------------------
Question 10

The famous church in the city of Kumbakonnam has a big clock tower and is said to be over 300 years old. Every Monday 10.00 A M the clock is set by Antony, doing service in the church. The Clock loses 6 mins every hour. What will be the actual time when the faulty clock shows 3 P.M on Friday?

(a) 4 A.M (b) 3.16 P.M. (c) 4.54 A.M. (d) 3 A.M

Answer : c) 4.54 A.M

Solution:

Total hours from Monday 10.00 AM to Friday 3.00 PM =101 HOURS

The clock loses 6 minutes every hour. In 101 hours it will lose 101 x 6 =606 minutes. ie 10 hours 06 minutes.

To find the actual time, calculate 10 hours 6 min backwards from Friday 3.00 PM which is 4 .54 AM

Hence the actual time would be 4 .54 AM when clock shows 3.00 PM on Friday.

Question 11

Brilliant software company, Chennai has been doing an excellent business in the last four years. The company went on a recruitment spree from among the engineering colleges in and around Chennai. They recruited people from ECE, CSE, IT streams. All programmers are of equal respect. They receive equal salaries and perform equal load of work. Suppose 15 such programmers take 15 minutes to write 15 lines of code in total. How long will it take for 84 programmers to write 84 lines of code in total?

a) 84 minutes b)15 minutes c) 27 minutes d) 30 minutes

Answer : b) 15 minutes

Solution :

For such problems where efficiency of the workers are alike, we can use the below equation :
P1 x M1 / L1 = P2 x M2 / L2 ...(1)
In the above formula, P1 and P2 represent number of programmers in I and II scenarios respectively ; M1 and M2 minutes required for completion of work in I and II scenarios respectively and L1 and L2 represent number of lines of code in I and II scenarios respectively.
Given values : P1 = 15, L1 = 15, M1 = 15, P2 = 84, L2 = 84. We have to find M2
Applying given values in equation 1 we get,
15 X 15 / 15 = 84 X M2 / 84
Simplifying we get, M2 = 15 minutes which is our answer.
------------------------------------------------------------------------------------------------------------
Question 12

One of the leading software companies recruited boys and girls from different engineering colleges.They were given training in software program writing for three weeks in the company’s fully equiped modern training centre.All of the employees developed similar skills , abilities and were paid equal salary. How many programmers would be required to write 48 lines of code in twice the time that would be consumed 12 programmers to write 12 lines of code ?

a) 12 b)24 c)15 d)10

Answer : b) 24 programmers

Solution :

Given Values : L1 = 48, P2 = 12 and L2 = 12
Also from question it is clear that time taken in scenario 1 will be twice that in scenario 2.
Therefore, M1 = 2M2
Substituting the values in our familiar equation (ref solution for question 1)
P1 X 2M2 / 48 = 12 X M2 / 12
P1/24 = 1
Or P1 = 24 programmers.
------------------------------------------------------------------------------------------------------------

Question 13

M/s. Compaware software systems had a revenue of US $ 747 million during the last year. It was in 34th position among the leading software companies. The company wanted to improve its business position and ranking and hence recruited 600 programmers afresh and gave them intensive training in software code line writing. After the training was completed all the programmers attain similar level of expertise in writing of software code lines and hence they were paid similar salary. Supposing 108 programmers can write 108 lines of software code in 108 minutes, 72 programmers will write how many lines of software code in 72 minutes?

a) 108 b) 60 c) 72 d) 48

Answer : d) 48

Solution :

Given Values : P1 = 108, M1 = 108, L1 = 108, P2 = 72, M2 = 72
Applying these values in our familiar equation (ref solution of question 1) we get :
108 X 108 / 108 = 72 x 72 / L2
L2 = 72 x 72 / 108 = 48 lines

Question 14
Somayaji Rao, retired Sub-Inspector of Police, Nandyal, Kurnool District, Andhra Pradesh has three grand children.The age of the eldest grand child is four times the age of youngest grand child. It is also seen that the second grand child’s age is half of the eldest grand child.The sum of the ages of all three grand children is 48.What is the age of eldest grand child?

a) 48 b) 24 c) 12 d) 30

Answer : b) 24

Solution :

Let the age of youngest grand child be X. Middle grand child age be Y and eldest grand child be Z years.
Given Z = 4X ...(1)
Also Z = 2Y ...(2)
From 1 and 2 we get, 4X = 2Y
Or Y = 2X

In terms of X the age of three grand children = X, 2 X , 4 X
It is given that the sum of the ages of all the three grand children = 48
X + 2X + 4 X = 48
X = 6
So youngest grand child's age = 6
Eldest grand child age = 4 X = 4 x 6 = 24 years
------------------------------------------------------------------------------------------------------------

Question 15

Four years ago, the age of Kamalhasan was three times the age of his daughter.The total of the ages of Kamalhasan and his daughter after four years will be 64 years.What is the present age of Kamalhasan?

a)40 years b)36 years c)60 years d) none of these.

Answer : a) 40 years

Solution :

Let the age of Kamalhasan before four years be K and that of his daughter be D
Four years ago K = 3 D ...(1)
If four years ago Kamalhasan's age was K, today his age will be K +4, after 4 years his age will be K + 4 + 4
If four years ago daughter's age was D, today her age will be D + 4, after 4 years her age will be D + 4 + 4
Four years afterwards the sum of the ages of the two will be 64 years.
So (K + 4 + 4 ) + (D + 4+ 4) = 64

But from eq 1, we know that K = 3D. Therefore above equation becomes
(3D + 4 + 4 ) + (D + 4+ 4) = 64
4 D + 16 = 64
4D = 64 -16 = 48
D = 12
So Kamalhasan’s present age = K + 4 = 3D + 4 = (3 x 12) + 4 = 40 years

Question 16

Brahmananda Sastri is grand father of three sons of his son. Nelson one of his grand son is three times older than another grand son Thompson. His third grand son James is not in station.He is studying in a school Ootacamund. Nelson’s age after three years will be six times the age of Thompson one year ago.What is the present age of Nelson?

a)6 b)12 c)9 d)15

Answer : c) 9

Solution :

The name of grand father and details about the third grand son are all time consumers.Candidates should be alert to read and consider only what is required to answer the question.
Let the present age of Nelson be N and the present age of Thompson be T
Then N = 3 T ...(1)
Nelson’s age after three years will be six times the age of Thompson one year ago. Formulating this in the form of equation we get,
N + 3 = 6 (T-1)

Substituting for N as 3 T (from 1) we get
3 T + 3 = 6 T – 6
3 + 6 = 6 T - 3 T = 3 T
9 = 3 T
3 = T
So Nelson’s age is 3 T = 3 x 3 = 9 years.

Question 17

The ratio of the ages of Mohanapriya and Kulandaivelu is 3 : 4.Four years earlier the ratio was 5: 7.Find the present age of Kulandaivelu.

a) 32 b) 24 c) 36 d) 40

Answer : a) 32

Solution :

Let the ages of Mohanapriya and Kulandaivelu be 3 x and 4 x respectively
Four years earlier the ratio was 5: 7
(3x - 4) / (4x – 4) = 5/7
Cross multiplying
20x - 20 = 21 x - 28
-20 + 28 = 21x - 20 x
+8 = x
Kulandaivelu’s age = 4x = 4 x 8 = 32 years
------------------------------------------------------------------------------------------------------------
Question 18

Sneha is engaged. Her Fiance is one amongst Abdul, John, King and Vimal. Sneha either speaks truth or lies. One of four men always speaks truth while others may or may not speak the truth. Now based on the below statements, can you find the Fiance ?
1) Abdul says "Sneha always speaks truth".
2) King says "Sneha always lies".
3) Vimal says "Sneha always speaks truth but only to him".
4) John says "The only truth speaking person amongst Vimal and John is Sneha's Fiance"

a) Abdul b) King c) Vimal d) John.

Answer : d) John

Solution :

From the question, we know clearly that Sneha can speak either Truth or Lies.
But as per statement (1) Abul says "Sneha always speaks truth". Hence this statement cannot be true. Hence our inference is that Abdul always lies.
As per statement (2) King says "Sneha always lies". Again this statement is false as Sneha can speak either Truth or Lies. Hence we can infer that King always lies.

On statement (3) Vimal says "Sneha always speaks truth but only to him". But there is no evidence / proof for this claim on data in question. Hence we can safely consider that Vimal also lies always.

In question it is clearly given that one of four men always speaks truth while others may or may not speak the truth. Since we have concluded Abdul, King and Vimal always lie, John should be the only truth speaking man.

According to statement (4) John says that "The only truth speaking person amongst Vimal and John is Sneha's Fiance". Since John is found to speak truth always, this particular statement from John should be absolutely True.
Also we have found earlier that Vimal always lies. Hence the truth speaking person John has to be the Fiance.
------------------------------------------------------------------------------------------------------------

Question 19

Three men Ravi, Ram, Rahul and two women Rekha and Padma were seated next to each other (not in order given) in a meeting. The arrangement was that the person who speaks definitely the truth will occupy the first position and the person who speaks definite lie always will be the last. The middle three positions will be filled by people whose statements may be truth or may be false. Can you find the correct arrangement from the options based on the statements below :
1) Padma says the probability of her occupying the 4th place is lesser than the probability of her occupying 1st place.
2) Rahul says that "Padma lies always when calculating probability"
3) Rekha says "Ram is the tallest of the 5 people"
3) Ravi says "He will be leaving early provided Rahul is a truth speaking person"
4) Ram says "He does not know probability"

a) Rahul - Ravi - Rekha - Ram - Padma b) Ravi - Rahul - Rekha - Ram - Padma
c) Rekha - Rahul - Ravi - Padma - Ram d) Rahul - Ravi - Ram - Padma -Rekha

Answer : a) Rahul - Ravi - Rekha - Ram - Padma

Solution :

Though the question looks bit difficult it is actually a simple question provided you can quickly extract out only required data and ignore irrelevant details.

All the options have different combinations for 1st and last positions. This means, if you are smart enough to find the person who always speaks truth and the person who always speaks lies, it is more than enough to answer the question.

According to statement I, Padma says that the probability of her occupying the 4th place is lesser than the probability of her occupying 1st place. But this cannot be true. This is because probability of Padma to occupy any given position is 1/5 . (1/5 is the probability of Padma to occupy any given position be it 1st or 2nd or 3rd or 4th or 5th positions). Therefore we can safely conclude that Padma is definitely lying.

According to statement 2, Rahul says "Padma lies always when calculating probability". This is a definite truth based on our conclusion in previous paragraph. We can safely conclude that Rahul speaks definitely the truth.

From the above two paragraphs, we can say that 1st position will be occupied by Rahul (as he speaks definite truth) and the last position will be occupied by Padma (as she speaks definite lies). Only option that has this combination is option a) and hence the answer.

Question 20

Mylapore Times a local free newspaper conducted a test for students studying in corporation schools falling within the jurisdiction of Chennai. The test was aimed at ascertaining the level of mathematics knowledge among the school students. The following question was given :
“How many numbers are there between 133 to 294 both included, which are divisible by 7?”

a) 23 b) 24 c) 26 d) none of these.

Answer : b) 24.

Solution :

In this problem both the boundary numbers 133 and 294 are divisible by 7. Also the boundary numbers are inclusive for calculation. In such scenarios solving is very simple.
Quotient 1 (when upper boundary number is divided by the divisor, in our case 7) : When 294 is divided by 7 we get 42. (1)
Quotient 2 (when lower boundary number is divided by the divisor, in our case 7) : When 133 is divided by 7 we get 19.(2)
Answer can be obtained using the formula, Quotient 1 - Quotient 2 + 1 = 42 - 19 + 1 = 24
42 - 19 = 23 + 1 = 24

Question 21

Porur Times is a newspaper which is distributed free to residents in and near Porur. It carries advertisement on different aspects such as rental, real estate, tuition, business deals etc. Porur Times gave a puzzle and wanted answers to be emailed to them within a day. The question read as under:
“How many three digit numbers can be formed using the digits 1,2,3,4,5 (but with repetition) that are divisible by 4?”

a) 12 b) 20 c) 60 d) 10

Answer : b) 20

Solution :

To solve this problem, we are going to utilize the simple rule that for a number to be divisible by 4, its last two digits must be divisible by 4.
Using digits present in 1,2,3,4,5 the two digit combination's that are divisible by 4 include
12, 24, 32, 44
Now placing any of the digits from 1,2,3,4,5 before the 2 digit numbers that we arrived in previous step, we can actually find the total number of 3 digit numbers formed from 1,2,3,4,5 that are divisible by 4.
They are,

112, 124, 132, 144
212, 224, 232, 244
312, 324, 332, 344
412, 424, 432, 444
512, 524, 532, 544
Therefore there are 20 numbers which is our answer.

Question 22

Kumaresh attended a placement examination online and the following question was posed to him:
“ The difference between the squares of two consecutive odd integers is always divisible by" which of the following:

a) 6 b) 8 c) 7 d) 3

Answer : b) 8

Solution:
Let the two consecutive odd integers be (2x + 1) and (2x + 3).
Then, (2x + 3)2 - (2x +1)2
4x2 + 12x + 9 - 4x2 - 4x -1 = 8x + 8 = 8(x +1).
Now for any value of x, 8(x +1). is divisible by 8. Therefore, answer is 8.

Question 24

For the IPL 5 cricket matches Mr. Bala Josiar has been predicting the winner of each match with amazing success. It is rumored that in a match between 2 teams X and Y, Bala Josiar picks X with the same probability as X's chances of winning. Let's assume such rumors to be true and that in a match between Rajasthan Royals and Chennai Super Kings, Chennai Super Kings the stronger team seems to have a probability of 3/4 of winning the game. What is the probability that Bala Josiar will correctly pick the winner of the Rajasthan Royals–Chennai Super Kings game?

a) 7/ 16 b) 9/16 c) 3/4 d) 10/16

Answer : d) 10/16

Solution :

Probability that CSK wins = 3/4
Probability that RR wins = 1 - Probability that CSK wins = 1 - 3/4 = 1/4
Probability of picking a winner = Probability of picking RR x Probability that RR wins + Probability of picking CSK x Probability that CSK wins
Bala Josiar picks with the same probability of a team’s chance of winning. This means, Probability of picking RR = Probability that RR wins and Probability of picking CSK = Probability that CSK wins

Therefore, Probability of picking a winner = (Probability that CSK wins)2 + (Probability that RR wins)2
= ( 3/4 )2 + (1/4)2
= 9/16 + 1/16
= (9 + 1) / 16
= 10/16
------------------------------------------------------------------------------------------------------------
Question 25

Mr. Randor Guy, the famous astrologer staying at Anna Nagar, Chennai has been able to predict the winner of each Hockey match with amazing success. It is told in the sports circle that in a match between two teams A and B, Mr. Randor Guy picks A team with the same probability as A’s chances of winning. But he seems to be incapable of predicting a tie. Let us assume such rumors to be true and that in a match between Pakistan and India, India the stronger team has a probability of 2/3 of winning the game. Based on past data it is also estimated that the probability of match getting tied is 1/9. What is the probability that Randor Guy will correctly pick the winner of the Pakistan-India game?

a) 4/9 b) 2/3 c) 52/81 d) none of these.

Answer : c) 52/81

Solution :

This question is very similar to the previous question, except the fact that there is a probability of tie as well.
Probability of India winning = 2/3
Probability of Pakistan winning = 1 - Probability of India winning - Probability of Tie
= 1 - 2/3 - 1/9 = 1 - 5/9 = 4/9
So probability of picking a winner = probability of picking Pakistan* Probability of Pakistan winning + probability of picking India* Probability of India winning + probability of picking a tie x probability of tie ....(1)

Randor Guy picks with the same probability of a team’s chance of winning.
Therefore, Probability of picking Pakistan = Probability of Pakistan winning, Probability of picking India = Probability of India winning. Also we know that he is unable to predict a tie. Therefore, probability of picking a Tie = 0.
Applying above in eq (1) we get,

probability of picking a winner = (Probability of Pakistan winning )2+(Probability of India winning)2+ 0 x probability of tie
= ( 4/9 * 4/9) + ( 2/3* 2/3) + 0
= 16/81 + 4/9
= (16 + 36) / 81
= 52/81
------------------------------------------------------------------------------------------------------------
Question 26

Om Navasakthi Astrologers , Chennai has been able to predict the winner of each football match with amazing success. It is told in the sports circle that in a match between two teams A and B, Om Navasakthi Astrologers picks A team with the same probability as B’s chances of winning and vice versa. Let us assume such rumors to be true and that in a match between Germany and Brazil, Brazil the stronger team has a probability of 4/7 of winning the game. What is the probability that Om Navasakthi Astrologers will correctly pick the winner of the Germany-Brazil game?

a) 24/49 b) 4/7 c) 18/49 d) none of these.

Answer : a) 24/49

Solution:
This is similar to earlier questions except the fact that Astrologers pick A team with the same probability as B’s chances of winning and pick B team with the same probability as A's chances of winning.
Probability of Brazil winning = 4/7.
Therefore, Probability of Germany winning = 1 - 4/7 = 3/7
So probability of picking a winner = probability of picking Brazil*Probability of Brazil winning + probability of picking Germany * Probability of Germany winning ....(1)

Astrologers pick A team with the same probability as B’s chances of winning and pick B team with the same probability as A's chances of winning.
Therefore, Probability of Brazil winning = probability of picking Germany and Probability of Germany winning = probability of picking Brazil

Applying this in eq (1) we get
probability of picking a winner = ( 3/7 * 4/7) + ( 4/7* 3/7)
= 12/49 + 12/49
= 24/49

Question 27

A Maruti Swift car started from Chennai towards Mumbai at 7 am. A Tata Indigo car newly purchased started from Chennai at 10 am towards Mumbai and the second vehicle was able to cross the first vehicle at 6 pm on the same day. If Tata Indigo was running at an average speed of 80 km per hour what would have been the speed of Maruti Swift car?

a) 64.24 km/hour b) 59.12 km/hour c) 58.18 km/hour d) 65.42 km/hour

Answer : c) 58.18 km/hour

Solution :

Tata Indigo car had taken 8 hours to cross Maruti Swift running at 80 km/hour.
Distance covered by Tata Indigo in 8 hours = 80 x 8 = 640 km
This distance has been covered by Maruti Swift in 11 hours (as it started at 7 am and was crossed by Tata Indigo at 6 pm)
So average speed of Maruti Swift - 640 /11 = 58.18 km/hour
------------------------------------------------------------------------------------------------------------

a) 78.75 km/hour b) 74.75 km/hour c) 72.50 km/hour d) 76.85 km/hour

Answer : a) 78.75 km/hour

Solution :

Ashok Leyland has run 10 ½ hours before the trucks met at an average speed of 60 km/hour
Distance covered by Ashok Leyland - 60 x 10 ½ = 630 km
This distance has been covered by Tata Truck in 8 hours (as it started at 8.30 am and crossed the other truck at 4.30 pm)
Average speed of Tata Truck = 630 / 8 = 78.75 km/hour
------------------------------------------------------------------------------------------------------------
Question 29

A Tata Indica car started from Hyderabad towards Madurai at 5.30 am and travelled at an average speed of 50 km/hour. An Innova car started at 8.30 am from Hyderabad again towards same destination at an average speed of 66 2/3 km/hour. At what time Innova will cross the Tata Indica Car?

a) 4.30 pm b) 5.30 pm c) 3.30 pm d) 6.40 pm

Answer : b) 5.30 pm

Solution :

Tata Indica starts at 5.30 which is 3 hours before Innova started. Therefore it has run for 3 hours at 50 Km/hr speed. Hence Tata Indica car has run 50 x 3 = 150 km by the time Innova starts.
The relative speed of Innova car = Innova Speed - Indica Speed = 66 2/3 - 50 = 16 2/3 km/hour
(Note: To calculate relative speed we are subtracting Indica's speed from Innova's speed as they travel in same direction. If they were travelling in opposite directions we would had added the speeds.)
Innova will take Distance/Relative Speed = (150) / (16 2/3) = 9 hours.
So Innova will cross Tata Indica 9 hours after 8.30 am i.e at 5.30 pm

Question 30

Mr. Kohli had a doubt regarding a situation and he approached Mahendra for clarification. The question read as under:--
One of four people –two men Raman and Krishnan and two women, Sonam and Kala -- were murdered.
Hint : Raman's sister is Krishnan's wife and vice versa.
1) Raman’s sister argued exactly once with Sonam’s legal husband after the murder.
2) Krishnan’s sister argued twice with the victim’s legal spouse after the murder.
Help Mahendran identifying the victim?

a) Krishnan b) Raman c) Sonam d) none of these.

Answer : a) Krishnan.

Solution :

1) Raman’s sister argued exactly once with Sonam’s legal husband after the murder.
2) Krishnan’s sister argued twice with the victim’s legal spouse after the murder.
From both the statements, we can see that the victim has to be a MAN as both the sisters were involved in arguments after the murder.
To solve such problems, we will have to assume a Victim and check the possibility of all statements. If even one of the statements is logically impossible then our nearest assumption would be false.

1) Assume Raman is the victim.
1a) Assume Raman's Sister is Kala
(If Raman's Sister is Kala then Krishnan's sister has to be Sonam. Also Raman's wife has to be Sonam and Krishnan's wife has to be Kala.)
As per statement I, Kala would had argued with Raman after the murder. – Impossible. (But since we have assume Raman is the victim this is not possible.)

1b) Assume Raman's Sister is Sonam
(If Raman's Sister is Sonam, then Krishnan's Sister would be Kala, Raman's Wife would be Kala and Krishnan's wife would be Sonam)
As per statement I, Sonam would had argued with Krishnan after the murder. - Possible
As per statement II, Kala would had argued with Kala after the murder.- Impossible. (Kala cannot argue with herself)

2) Assume Krishnan is the victim.
2a) Assume Raman's Sister is Kala
(If Raman's Sister is Kala then Krishnan's sister has to be Sonam. Also Raman's wife has to be Sonam and Krishnan's wife has to be Kala.)
As per statement I, Kala would had argued with Raman after the murder. - Possible
As per statement II, Sonam would had argued twice with Kala after the murder. – Possible
All the statement hold good if Krishnan is the Victim provided Raman’s sister is Kala.

2b) Assume Raman's Sister is Sonam
(If Raman's Sister is Sonam, then Krishnan's Sister would be Kala, Raman's Wife would be Kala and Krishnan's wife would be Sonam)
As per statement I, Sonam would had argued with Krishnan after the murder. – Impossible (as we have assumed Krishnan is the victim)

Question 31

Consider the below statements. One of the friends is lying while others are saying the truth. Find the person who is lying.
1) Ram says he is taller than both Ravi and Rahul

2) Raju says he is not taller than Ram and Ravi

3) Rahul says he is taller than Rajan and also adds he is neither taller nor shorter than Ravi

4) Rajan says he is taller than Ram

5) Ravi says he is taller than Rajan

a) Ravi b) Rajan c) Ram d) Rahul e) Raju

Answer : b) Rajan

Solution :

Based on the statements given, let us start arranging the people in order of their heights.

As per statement 1, Ram is taller than both Ravi and Rahul. Also from second part of statement 3, we can easily say that Rahul is equal in height to that of Ravi.

Arrangement : Ram, Ravi, Rahul

As per statement 2, Raju is shorter than both Ram and Ravi

Arrangement : Ram, Ravi, Rahul, Raju

As per statement 3, Rahul is taller than Rajan

Arrangement: Ram, Ravi, Rahul, Rajan, Raju (as of now we will assume Rajan is taller than Raju)

As per statement 4, Rajan is taller than Ram,

Here is the catch! Rajan is clearly shorter than Ram from statements 1 and 3. Now if we assume Rajan is speaking the truth then we will have to conclude both Ram and Rahul are lying. But the question clearly says only one of the friends is lying. Hence statement 4 is false and Rajan is lying.

(Additional Information : As a matter of fact, Ravi is also saying truth as his statement perfectly falls in line with the arrangement we made so far...)
------------------------------------------------------------------------------------------------------------
Question 32

Consider four brothers A,B,C,D. A is the eldest of all.
The immediately younger brother to A always plays with the youngest brother among all four.
D is the immediately elder brother to the youngest brother.
Find the brother who is immediately younger to A.

a) B b) C c) either B or C d) can’t be determined

Answer : c) either B or C

Solution :

It is given that A is the eldest of all and D is immediately elder to the youngest brother.
Hence one among B and C has to be the youngest and the other one has to be immediately younger to A. But data in question is insufficient to arrive at the right person amongst B and C.

Tata loses case against 2 employees in US wage suit

2012-06-07T08:13:00.001-07:00

Tata Sons Ltd employees who were deployed from India to work in information technology jobs in the United States won the right on Monday to proceed with a class action lawsuit against the Indian corporate giant over unpaid wages.

California federal judge Claudia Wilken granted class-action status to the suit that accuses Mumbai-based Tata and its subsidiary, Tata Consultancy Services, of breaching employee contracts and violating California labour laws

Two former employees accused the company in 2006 of forcing all non-US-citizen workers to sign over their US federal and state tax refund checks to the company. Tata also deducted their Indian wages from their compensation, the suit alleged.

The judge authorised one national class of plaintiffs, comprised of non-US citizens who worked at the company between 2002 and 2005, to sue for contract violations. The court certified a separate class of employees to bring claims under California labour laws.

"More than 10,000 current and former Indian nationals working for Tata in America now may have their day in court," Kelly Dermody, a lead attorney for the employees, said in a statement.

Robert Steiner, a lawyer for Tata America International Corporation with Kelley Drye & Warren, did not respond immediately to a request for comment.

Tata Sons Ltd is the holding company for salt-to-software conglomerate Tata Group, India's biggest corporate house.

TCS faces class-action lawsuit in US

2012-06-07T08:05:00.001-07:00

An article about TCS

Two former employees of the IT giant who were sent to the United States complained over unpaid wages.

It’s now the turn of India’s largest information technology (IT) services provider, Tata Consultancy Services (TCS), to face litigation heat in the US. A complaint filed by two former employees of TCS over unpaid wages has been accepted by a US court as a class action lawsuit.

US District Court Judge Claudia Wilken issued an order that granted class-action status to the suit that accused Tata Sons and its subsidiary, TCS, of breaching employment contracts and violation of the California Labour Code.

The complaint was filed by non-US employees Gopi Vedachalam and Kangana Beri, who were sent from India to the US to work on projects.
TCS said in a statement, “We have received the order of the US District Court. This is an order only on one procedural matter and does not address the merits of this case. TCS continues to believe that when this matter concludes, the court will find that the plaintiff’s claims are without any merit.”

On February 14, 2006, Lieff Cabraser Heimann & Bernstein filed a nationwide class-action lawsuit against Tata. The suit charged that Tata unjustly enriched itself by requiring all of its non-US citizen employees to endorse and sign over their federal and state tax refund checks to Tata and by taking unauthorised deductions from employee’s paychecks.

The complaint also alleged that Tata did not pay its non-US citizen employees the amount promised to those employees before they came to the US. In standard employment contracts, TCS promised to pay its employees a gross US salary and a separate Indian salary. The company’s unauthorised deductions from its employees’ wages prevented employees from receiving both their promised US salary and Indian salary.

“More than 10 thousand current and former Indian nationals working for Tata in America now may have their day in court. We look forward to demonstrating at trial that Tata breached the standard employment contract with these employees and violated California labour laws,” said Kelly M Dermody of Lieff Cabraser Heimann & Bernstein, LLP, and co-lead class counsel.

In June 2006 and April 2007, Tata America International Corporation and its parent corporations, TCS and Tata Sons, filed a motion to dismiss the case, arguing the case should be arbitrated in India rather than the US. Lieff Cabraser opposed the motion. In November 2006 and June 2007, the court heard oral argument on the motions and took them under submission.

Plaintiff Vedachalam said, “I am very happy with the court’s decision today. It means my former colleagues and I are one step closer to holding Tata accountable.”

Employee activism
TCS will not be the first Indian company to be pulled up by a US court. Jack Palmer, an employee of Infosys, filed a case against the company, alleging the Bangalore-based IT services provider was involved in misusing the B1 business visa programme to send lower level and unskilled foreigners to the US to work in full-time positions.

The case is expected to come up for hearing on August 25. Infosys has maintained it has not done anything wrong and will cooperate with the investigation.

“The judge has certified it as a class action, which means that all employees who fall under the fact pattern can join the litigation. I don’t think this litigation has anything to do with anti-India sentiment rather than lawyers who try to bring novel legal claims on behalf of employees, and Indian firms seem to have become an easy target. This is because tax and visa rules involving foreign workers on temporary visas, who are also employees of the IT firm in India, are amorphous and subject to varying interpretation,” said Cyrus Mehta, an immigration lawyer and founder of Cyrus D Mehta and Associates.

In July last year, Cognizant Technology was dragged to a US court, as eighteen former employees of Molina Healthcare filed a lawsuit against the American healthcare services firm for allegedly replacing them with professionals from India. Cognizant had said it would “vigorously contest” the same by pursuing all legal remedies.

In 2006, Infosys was also accused of violating California’s labour laws for allegedly failing to pay overtime wages to its immigrant employees there. A Californian law firm was said to have warned the company of filing a class-action suit against it. However, the IT company settled the issue amicably, by agreeing to pay $26 million in total towards the overtime payment what it had announced earlier.

TCS CEO and MD N.CHANDRASEKARAN sharing his Successful Story

2012-06-04T07:17:00.002-07:00

An article in HINDU about the success story of TCS CEO

Natarajan Chandrasekaran’s smile lights up the huge LCD screen, visible clearly even though we were sitting around 1,500km apart. I was in his branch office in New Delhi while he was in his Mumbai office—we were on video chat. On his desk were family photographs of his trekking getaways in the Himalayas and some mementos he has collected over the years—the few adornments he allows in his simple yet elegant office—besides his electronic gadgets and personal computer.

Chandra, as he is fondly called by colleagues and friends, had ample reason to smile that day. His company, Tata Consultancy Services Ltd (TCS), had declared robust results for the March quarter on 23 April, the previous day, and the overall revenue of TCS, already the largest Indian information technology (IT) services provider, had crossed $10 billion (around Rs. 53,700 crore now).

TCS’ revenue today is 10% that of the entire IT industry (including domestic hardware) in India—$100 billion, according to software lobby body National Association of Software and Service Companies, or Nasscom. It had an employee strength of 238,000 as on 31 March—also around 10% of the IT industry’s direct employment figures in the country, according to Nasscom.

Chandrasekaran, TCS chief executive and managing director, also took over as Nasscom chairman for 2012-13 from 1 May. He was its vice-chairman in 2011-12.

“Over the last 40 years, we have created a solid platform,” says Chandrasekaran. “The company has depth and we have learnt to take risks while remaining agile. We also have developed a culture of building long-term relationships and have created many job opportunities over the years (TCS will surpass the 250,000-employee mark in the next few quarters).”

Easy-going: Despite his love for impersonal math and numbers, Chandrasekaran is considered by his colleagues to be affable and approachable (Jayachandran/Mint)
He adds in his typical unassuming style: “This is indeed a milestone. So, will $15 billion and $20 billion and so on be further targets? But that’s not the point. The IT industry throws up a lot of opportunities and we will leverage our scale to stay focused on these opportunities to grow further.”

Globally, technology company Hewlett-Packard, or HP, has an annual revenue of around $125 billion while IBM is an approximately $107 billion company. In India, however, the revenue of these companies is not strictly comparable with Indian IT firms since companies like TCS, Infosys and Wipro cater primarily to the US and UK markets. However, for the purpose of comparison with a company like TCS, IBM Global Technology Services (the outsourcing division of IBM) is a $40 billion unit, while Accenture Plc.’s revenue is a little over $27 billion.

In the country, according to the Dataquest magazine’s DQ Top 20 domestic IT players ranking (released in September 2011), HP India had a revenue of Rs. 19,022 crore while Cisco India posted a revenue of Rs. 7,015 crore.

The impression one gets on meeting Chandrasekaran is that IT services is what he was always meant to do. He has been with TCS for almost 25 years. He never applied for any other job, starting at TCS as a software programme in 1987.

But that’s not the case. He could easily have been a farmer had he succumbed to his father’s wishes in the early 1980s.

“I was one of six children. My father was a lawyer but when my grandfather died, my father had to look after the family properties that included farmland. I went to a Tamil-medium school till class X. Being a typical Tam Bram (short for Tamil Brahmin), I excelled in math. After my 10th standard, I moved to Trichy (in Tamil Nadu) to study further and had to stay in a hotel (it was not a hostel, he clarifies) near the school. I used to go back home every six weeks. So far, I had led a protected life. This experience came as a big change in my life,” recalls Chandrasekaran.

After a bachelor of science (BSc) in applied sciences from the Coimbatore Institute of Technology, Chandrasekaran went home and stayed back six months, “to see whether I could take up agriculture as a profession. After four-five months, I realized that agriculture was not my cup of tea,” he reminisces. “I then thought of becoming a chartered accountant. By then, I had missed an academic year.”

By this time, however, the government had introduced computer education in colleges—and this was to change his life. Chandrasekaran persuaded his father and went on to complete his master’s in computer applications from the Regional Engineering College, Trichy, in 1986.
In the final year of his master’s programme, he took up a project with TCS, and never looked back—starting as a software programmer and rising to the helm of the company where he learnt the ropes of the IT business. In October 2009, he succeeded S. Ramadorai as CEO and MD of TCS at age 46, becoming one of the youngest CEOs of the Tata group. It was Ramadorai, now vice-chairman of TCS, who groomed Chandrasekaran for a leadership position.

His rise in TCS was fast. In 1999, he started the firm’s e-business unit and grew it to an over $500 million segment in four-and-a-half years. In September 2007, he was co-opted on the TCS board and named the chief operating officer (COO) of the company. As the COO, he drove the company’s acquisition strategy—the acquisition of Citigroup Global Services for $505 million in October 2008 is credited to him.

The transition was well-planned. Chandrasekaran was one of the best-kept secrets in the TCS citadel; he was identified for the CEO’s role around 2004-05, insist analysts. But his public role became apparent only somewhere around 2007.

Has his role changed drastically—from a manager to a leader? “I do not have any classical definition. But a leader must have the ability to dream, to take risks and be accountable. Besides, a leader should be able to build trustworthy teams and inspire them. A manager, on the other hand, must be exemplary in execution, articulating and simplifying things,” he says.

How does he manage his time, juggle so many roles (he is on various other bodies like the Confederation of Indian Industry), and yet remain calm?

“Firstly, I am enjoying my current role. I also use many gadgets to streamline my activities (Chandra is an Apple Inc fan and uses the latest iPhone and iPad to schedule his appointments). The technocrats at TCS help me optimize the use of gadgets, so I’m in a privileged position. I also get to learn much from my clients,” says Chandrasekaran, who lives in Mumbai with wife Lalitha and son Pranav, who is in class X. Lalitha left her job as an investment banker 15 years ago after marriage.

To de-stress, he reads fiction and books on politics and business. And he takes part in marathons too—2008 (Mumbai), 2009 (Mumbai, New York), 2010 (Chicago) and 2011 (Berlin, Boston). He has also run around eight half-marathons. “Running has helped me become a better listener. It also calms me and gives me time to reflect on issues,” he says. He takes running seriously, and began training 10 months ahead of the 2010 marathon.

Chandrasekaran is also fond of south Indian classical music and lyrically rich old Tamil film songs that remind him of his home in Mohanur village in Tamil Nadu. So does he get enough time with family? “You always want to spend more time with the family. We take a couple of breaks in a year,” he says.

TCS moved to 16th rank

2012-05-31T06:30:00.000-07:00

NEW DELHI, MAY 7:
Three out of top five Indian IT firms have moved up the global ranking in terms of revenues in 2011.

According to Gartner, Tata Consultancy Services (TCS) moved to rank 16 in 2011 compared to 21 in 2010, Cognizant has moved to the 27th spot compared to 30 in 2010 and HCL Technologies also moved up to rank 46 during 2011 against its 48 in 2010. Infosys and Wipro have held their last year's ranking of 26 and 31, respectively.

Market share of these five companies grew to 3.5 per cent in the worldwide market in 2011 compared with 3.1 per cent in 2010.

Overall, these companies grew at 23.8 per cent in 2011 as compared to 7.7 percent growth of the global IT services market as a whole. However, Gartner did not have any figures of previous year to compare with.

During the year, Cognizant displaced Wipro to become the third-largest Indian IT services provider that experienced the highest growth rate of 33.3 per cent amongst the top five providers in 2011.

TCS grew by 29.4 per cent, while second ranked Infosys grew by 17.8 per cent. Wipro had grown with least percentage at 12.3 per cent during 2011.

HCL Technologies also had a healthy growth with 26.2 percent, Gartner said in its report.

“Indian providers have historically found it more difficult to gain market share in the Western Europe IT services market than in the US market. But, as a group, the top five increased market share in the region from 2.3 per cent in 2010 to 2.8 per cent in 2011,” Principal Research analyst at Gartner, Mr Arup Roy, said.

He said 2011 signalled a change in mind-set of European buyers, particularly Continental Europe for offshore services.

The report said that on average, the tier 1 companies outperformed growth rates of tier-2 and tier-3 providers, despite consolidation and acquisitions among some of the smaller firms.

There were some standouts, however, with Genpact rose 27 per cent and Syntel up 21 per cent. Smaller providers were charged with creating a more compelling marketing message that went beyond labour arbitrage, it said. “In the past five years, they have been increasingly winning large outsourcing deals with a total contract value of more than $ 100 million. Their target customer segment still remains the Fortune 1000 companies, which is their ‘sweet spot',” Mr Roy said.

However, in recent years, these top five providers have greatly expanded their service portfolios and have been cross selling and up selling their application services client base with offerings such as infrastructure services, business process outsourcing (BPO) services, cloud and analytics services, he added.

-Bathroom had a broken commode seat (in two halves), the pipes leaked so that when you flushed the water would squirt straight at your face, the basin tap was weird. If you opened it the water would squirt out sideways at almost 90deg. I had never seen anything like that. After being drenched and using the commode I relaxed on the bed. I was afraid of what would happen since I didnt know how strict it would be in TCS and whether it would be ok ..

Food was not bad, (later on, after a few days, we heard the news that someone had spotted a cockroach in the food, haha but it was ok. After all this was the first job of my life!)

On the next day, we attended at KIIT auditorium for documents verfication(PAN Card, Degree,Affidavit etc) for next 2 days.After that our classes start at Koel Campus , KIIT.
Everyday thousands of PPTs are created and half of them was screwing the trainees.. We were given a desktop of PPT's to study all through the day..

Classes consists of 45 days includes 2 compulsory test (EC1 & EC2) and Brain Bench etc.
Both the test EC1 & EC2 are utmost important to get arrgegate 50% marks out of 200.
EC1 consists of programmimg language where only error finding , output of prg are to be asked in test.Dont go for programmimg ....do smart Study only and go for the only ppt which were given by TCS , it is more than enough.
EC2 consists of Java .Get ur concepts more clear on Encapculation, Aggregation, Association ,Normalization and little bit concept of programming on Java. Question will related to theory not like EC1.
In both Test u have to score above 50% aggregate.I got 97% and finally qualify for the phase 2 training at base center .

Had different experience during ILP with people from different states.Had lot of fun too both at villa and in office.All of us had a trip to NandanKanan Zoo.Then we visited few places like Konark,Puri temple and Piply where we bought some handicraft items.Missed few places like Chilka lake due to shortage of time. The places were greenish in and around Bhubaneswar,Ever raining,Early bird and Early Owl.Any way life was good

Overall TCS ILP training is something like smart training and tough for those who dreams that now TCS will not kick them out... All the best :-)
